# GET /v2/leagues/{id}/cup-trees

Group: Leagues

The season’s knockout brackets — a cup’s knockout stage, playoffs, a tennis draw: rounds → ties → the two participants (team, seed, winner, score) → our fixture ids.

Note: score is the source’s figure for the tie: aggregate goals over two legs (football), games won in a series (basketball, ice hockey), sets (tennis); penalties = shoot-out goals. fromBlock is the order of the previous round’s tie the participant came from; team null = a placeholder slot (“winner of QF 1”); matchCount 0 = a bye. Fetch the fixtures with /v2/fixtures/{id}. An empty array when the season has no knockout stage.

## Parameters

| Name | In | Required | Description |
| --- | --- | --- | --- |
| `id` | path | yes | our numeric id (positive integer) |
| `season` | query | yes | a season id from /v2/leagues/{id}/seasons |

## Response

- `data`: `CupTree[]`
- `meta`: season, count
- Objects: CupTree (https://sportsapi.app/markdown/en/reference.md#cuptree)

## Errors

- 400 bad_request — missing or invalid season
- 403 history_not_in_plan — the season ended before your plan’s history
- 404 not_found — season is not one of this league’s seasons (the message names the parameter; list them with /v2/leagues/{id}/seasons)
